To all whom it may concern:

Be it known that we, EDWARD WAUGH and WILLIAM J. Swan'rz, citizens of the United States, residing at Seattle in the county of King and State of Washington,

have invented certain new and `useful Im,- provements in Preparing A? aratus for Confectionery, of which the oilowing is a specification.

Our invention has more particular reference to apparatus designed for the preparation of candy mixtures and has for one of its objects to provide a novel mechanism whereln the -raw material or materials are reduced by heat to a 'semi-liquid `or molten condition.

The invention has for a further object to provide improved mixing and reducing mechanisms.

Further objects of our inventionreside in the production of a machine of this character 'which is efficient and economical in operation.

These'and'other objects, as willhereinafter appear, are obtained in the construction shownin the accompanying drawings. Such construction, while a preferred embodiment of our invention,'is susceptible of various changes or modifications without departing from lthe spirit of our invention which is particularly-defined in our annexed claims. Y

In the drawings, wherein like characters of reference indicate like parts throughout:

Fig.r12 is a ,verticalsection of the reducmg apparatus and feeding device, taken at right angles to Fig. 11, with a portion of the rotary grinding member broken away, and

Fig. 13 1s a fragmentary section of the pump caslngs L taken on line 13-13 of Fig 11.

or the purpose of illustration we have shown 'our .invention in conjunction with no`v el depositing mechanism, forming the subjectv matter of ourV application, Serial No. 74.3,'118, filed January '20, 1913. This comprises companion parts, 1,2, and 3, the latterl of which is movable with respect to the first two named parts for controlling the int-alie' and delivery of theI confectionery mixture with respect to the depositing devices of the mechanism. l

In our present construction we have disclosed a plurality of depositing devices comprlsing chambers 4 and plungers 5, from which the semi-liquid mixture is discharged intermittently onto an underlying carrier 6, which latter is of convenient length to insure of the deposits or products having ample time to cool andV harden prior to their removal.

Carrier 6 comprises an endless belt taking over drive and idler rollers 7 and 8 respectively, the former of whichis journaled in the main frame 9 of the machine and the latter in suitable stands 10.

Fixed to the axle of roller 7 is a ratchet wheel 11 with which a pawl 12 engages for imparting a step by step movement to carrier'G. Pawl 12 is pivot-ed'on an angle lever 13, swingingly mounted on the axle of roller 7 and 4connected to a driving rod 14 which latter is provided with a suitable strap encircling an eccentric 15, fixed to a driven shaft 16, journale'd' on frame 9.

and is conveniently formed with the chamceiying respectively companion-part 2 and a protuberance 1 of part 1, of .correspondi ing cross sectional contour, for sliding move- -ment thereon.

Companion part 2 is fixed to bracket extension 2 of a transverse 'frame member 9 and formed with ports 2" adapted for registration with suitable delivery' ports 4' 4of cham-bers 4.

Companion part 1 is shown as an integral part of a plurality of hoppe'i's or containers 17 for the repaired mlxt-ure and leading from these lioppers or containers thro'ii h part 1 are delivei-y-ports' 18 withwhich suitable ports 4" vofchamber's 4 areadnpted -to register. In this'connection it will be observed that ports 18 are arranged at oneA side of the related ports 2l so that4 colnmunication between the chambers 4 and their ports 18 will be established only when chamber ports 4 are closed against delivery by companion part 2. It 'will further be observed that the bottom walls of h'oppers or containers 17 and the delivery ports 18 thereof are inclinedJ thereby enablinv of the molten or semi-llquid material, if 1t be of the proper consistency, flowingby .gravity to the chambers 4. This however, un-

der usualconditions, can hardlybe depended upon to insure ofthe proper and uniformly perfect 'feed of the material to the chambers, Therefore, 'we through the mechanism .to be described, canse plungers .5 to move, .upwardly or on their suction stroke subsequently to the establishment of comnn'i'nication between ports 18, 4 at whichrtime part or slide'3 will be at rest. Another pause Aof part or slide 34 occurs when ports 4', 2 are in registration and at this time lun'gersv are moved downwardly or inwar -ly to eject the material which falling on carrier 6 will, unless suitable molds are provided on the carrierT assumei the form of .thin :disk-.like bodies. All of" the 'chambers -1 discharging simultaneously, the discharged predeterminedquantitiesof material will li'e on carrier 6 in' aj'taii's'versely extending'row, as will' be' apparent. A step like movement of carrier V6 now occurs to advancethe deposits from beneath part 2. P lun ers 5 are connected to a head 19,

pivotaly connected by rods, lformed of ar ticulated sections 2 0, 2 0', with arms 21 fixed to a rock shaft 22, journaledon frame '9. To per-mit of the normal set ofplungers 5 being varied we'adjustably connect rod .sections 2 0 with' arms 21, this being accom- 'lished 'b' l o\ 'e;r 'en portions; of the rodsections and loosely.engaging the same inblo'cks 2 3 which are pivoted' m the arms-21and engaged by nuts 24 mounted on the -`rod sections Pata 0 1 .aides is, .pivotal-1y connected a 25- .wheel 39.

external-1y screw threading the with actuating mechanism consisting of a lever 26, fulcrumed at 27 and havin its lower end v rtion pivotally connected lo an actuating slide 28, convementl guided, for horizontal movement, on fixedY pins 29 of frame 9.

Reference numeral 30 indicates a second actuating slide arranged at right an les to slide 28 andl below the same and gui ed for horizontal movement on guide pins 31 of frame 9.

Actuating slide'SO transmits motion to a l bell crank lever 32, fulcrumed at 32 and connected by a link 33 with an 34'of rock shaft. 22,` The connection between bell crank lever 32 .and slide 30 is such that the set ofthe bell crank can be varied in `conformity wit-hany adjustment desired to vary the stroke or length of strokel of plungers 5. This connection consists of a slide block 35 slidably engaged in a slot of the lever.

Reference numeral 37 indicates a screw rotatably mounted on actuating slide 30 and having screw threaded engagement with slide block 35. This screw is rotated, to advance pin 36 along the slot of the bell crank lever, through bevel caring 38, one of which gears is fixed to a saft suitably journaled on slide 30 and provided with a hand Actuating slides 28 and 30 are provided with followers 28', 30 whichengage -in the groove of a drive cam 40, loosely mounted on, shaft 16, and. adapted to be connected therewith byfa suitable clutch 42.

The groove of cam 40 `has'alternating throw and rest portions (see Figs. 9 and 10) all of substantially the same length, and followers 28', 30 being set to engage in said roove at substantially 90 apart, one folower will `obviously bejust leaving a throw portion on the cam as the other follower enters the same, thereby giving the pause to oneactuatin slide during thel operating of the other. 'I

ation of part orslide 3 and head 19, the upper rod sections 20 connected with head 19 shaft 43 through meshing gears 46, 46 on the respective shafts.

In accordance vwith our present invention we provide melting or cooking chambers 50, 50, 51, 51. Each of the chambers 50 com- .municates with -a respective one of the chambers 51 through upper and .lower po theA former of which ports, which 'also s'egtvsd isl mechanism effects the oper-V as vents, are closed by valves 52, yieldingly held closed by s rin 53, while the said lower ports are ose by manually opened valves 54, having their stems threaded in the Walls of the ad'acent lchambers 50 and conveniently provi ed on their projecting end portions with hand wheels 55.

Extending around the upper portion of' struction, we can fill both the chambers 50 and 51 with material to be melted, as will hereinafter be more fully set forth, and utilize such of the steam and moisture as may escape from the chambers 51 upon opening of valves 52 in chambers 50,

thereby obtainingl an expeditious treatment of the material in an economical manner.

Chambers 51 are connected by passages 57, controlled by suitable valves 58 having operating handles 58', with apparatus for reducing the semi-liquid or syrupy mass to a creamy consistency, now to be described.

This comprises a vertically disposed cylindrical chamber 59 having its inner face formed with spiral grooves 59 and snugly receiving a rotar grinding member or vice 66 which is ormed with spiral ribs 66 preferably of greater pitch thanthe grooves 59 and winding oppositely from the latter to act conjointly for reducing any solid par-` ticles inthe mass as well as advance or elevate the latter. We have shown the i'ibs spaced farther apart than the grooves, such arrangement having been found eicient in practice.

Disposed between passage 57. and the baseV of the reducing apparatus is a pair ofpumps 67 of the rotar type, each comprising a pair of opposite y rotating pistons or impellers 67 operated by a gear 78', on shaft 78, and arrangedv in a casing 67". A port 58, the upper surroundingedge of which forms a seat for valve 58,.connects passage 57 with acasing 67" on the remote side of the pistons from the inding member 66. The mass will there ore be divided and impelled by.' the pistons to the central casing 68 which surrounds gear 78 and connects the pum casings 67". Casing 68 is joined to c amber 59 by inwardly tapering side walls 68.

A drain off valve or cock 105 is provided below each port 58p, the same being advanced to and from a closed position by operable independently of the valve by a pnionlS, engaging a rack 108 of the rod, to enter the port 58"V to clean the same.

Chamber 59 is surrounded by a water jacket 60 and communicates at its upper end portion with a main suppl chamber 61, provided with a plurality of discharge ports 61', controlled by valves 62, and each communicating with a respective flavoringy or coloring container 63 which containers in turn communicate through ports 63', controlled by valves 64 with the adjacent hoppers or containers 1 Within containers 63 are stirrers these comprising upper and lower supports 69 fixed to vertical shafts 70 and havin rotary bladed members 71 journaled in their outer end ortions. These members `71 are each provided with three blades and being journaled in su ports 69 will during rotating of shafts 70, e rotated about their own axes through counter action of the material and thereby tend to always direct the latter inwardly away from the side walls of the containers, in a manner insuring a more perfect mixin action.

Shafts 0 are connected through bevel gearings 72 with a cross shaft 73 journaled on bracket' extensions of chamber 61, and driven through gearing 74 from a vertical shaft `75, which latter is provided on its lower end ortion with a bevelgear 76 meshing wit a loose gear 76 adapted tobe connected to shaft 43 by a suitable clutch 77.

Reference numeral 78 indicates a shaft fixed to rotary device 66 and having its lower end stepped in .a suitable bearing 79. This shaft is connected through gearing 80, an intermediate shaft 81 and gearing 82 with shaft 43, one gear of the lgearing 82 being' (preferably loose on shaft 43 and adapte to be 'made fast thereto by a clutch 83.

For cooling the material While being acted upon by device 66 we provide a rotary pump 84, of any suitable type, which is connected with shaft 44. This pump `is connected by pipes 85, 86 with a cold water tank 87 and water `jacket 60 respectively.

Reference numeral 88 indicates a return pi e leading from water acket 60 to tank 87.

eference numeral 89 indicates a hot water jacket for containers 17, 63 and chambers 61, 51, the same having a fillingaperture, closed by a plug 92, and being provided with suitable heaters, asl 90 'conveniently electric heaters of any well` known type which have their resistance coils inclosed to prevent access of the water. Similar heaters, as 91 are also provided in cooking chamber 51. y,

` In the operation of our invention, as when it is desired to produce `a simple creamy candy, We open valves 54 and then insert through the ports controlled thereby a redetermined quantity of sugar to whic is added water. Said valves 54 are then closed and chambers 50 filled or partly filled with sugar to which is added a smaller uantity of water than was placed in cham ers 51. Heaters 91 are now rendered active to bring about the desired temperature in chambers 51, as for example242 F. As these chambers 51 are vented through valves 52 open- A ing automatically, as hereinbefore set forth, the escaping steam passes through the contents of chambers 50 thereby serving to heat and start the melting step, which will be completed in chambers 51, as will be understood in the following.

When the mixtures in chambers 51 have been melted, first one valve 58 is opened, then the other, to insure of a practically constant flow to chamber 59. As one chamber 51 empties, it is refilled by opening valve 54. t

Valves 62 and 64 are conveniently pivotally supported and provided with handles 62, 64 respectively, whereby they can be opened to admit the mixture to the containers controlled thereby. Prior to the opening of valves 64, fla-vering or coloring ingredients will have been worked uniformly into the mixture by the stirrers in containers 63.

Angle lever 1.3 is oscillated continuously and on its active stroke advances lcarrier 6, as hereinbefore set forth.

If desired we may provide a removingl device 100, in the form of a scraper, which will remove the direct the same into a suitable receiverlOl, of any suitable construction.

slightly modified construction. form the carrier or belt has its upper face formed with molding ridges or corrugations 6 extending in the direction of its length, these serving to form the bottoms or'underfaces of the candies or products in a desired manner, whereby when the products are arranged in rows or in abutting relation to one another, channels or passages between the same, for the free circulation of air, will exist.
